ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTThe Dock & Keyboard
Despite what ASUS originally told us when it launched the first Transformer, the Prime does not work with the old dock. Admittedly you wouldn't want to use the sleek new tablet with the clunky old dock, but I'm just not a fan of being used to convey incorrect information.
The new dock matches the Transformer Prime perfectly. The docked Prime isn't as elegant as the Zenbook and I'd argue that the dock does take away from the tablet's beauty, but if you need to hammer out long emails or a big document the dock is a great solution.
The dock's beauty isn't just that it's convenient (it behaves just like a notebook once mated to the tablet) but that it acts as a second battery for the Eee Pad. ASUS has also done the necessary customizations to Honeycomb to appropriately track battery levels in the dock and the tablet. There's also a little animation indicating that the dock is charging the tablet. To the best of my knowledge, the tablet will never be used to charge the dock.
Scrolling is rarely as smooth as I'd like it to be via the dock's trackpad. Many times the gesture just won't register on the trackpad or the trackpad will detect my two fingers but it won't scroll. With the screen inches away I found myself preferring to use the touchscreen for scrolling and stuck to using the dock for typing. You can control pointer speed and cursor style in the OS now, which is a nice addition.
The typing experience itself is great on the dock. The keys are big enough (around 15mm x 14mm) to type quickly on and feedback is good. The keys were a bit taller on the old dock, but as the new model is thinner the keys went on a similar slimming process.
Using the dock on a desk is fine, but use the dock on your lap and you'll have to keep applying a little bit of downward force with your wrists to keep the system from leaning backward. The dock is angled forward so if you're not typing on a flat surface the system might pivot backwards. The correction is simple, you just need to push down with your wrists/palms a bit while you type. I even have to do that a bit on my 11-inch MacBook Air. The difference is the MBA has enough surface area for me to comfortably rest my wrists, the Transformer Prime's dock does not. While I don't notice much fatigue while typing on my MBA, my wrists do feel it when I use the Prime + dock on a couch.
My dock had a connection issue between the Prime and the dock itself, which ASUS insists shouldn't be happening. Tilt the Prime towards you when in the dock and the screen would occasionally go white. It feels like a manufacturing issue, although I'm apparently the only one who has reported it.
Android is still not beefy enough to be a full blown laptop replacement, but the Prime does come with enough apps to at least let you do some basic word processing and spreadsheet work. If you're going to do a lot of typing on your tablet I'd easily recommend the dock, it's the best way to get your thoughts into words on the Prime. Otherwise, the $150 adder just adds bulk and cost to the platform. The Prime is really great to use on its own. If you want an alternative to the dock, ASUS will have its own clone of Apple's iPad smart covers at some point in the coming weeks.
ASUS' five row virtual keyboard is back on the Prime. While it doesn't look as good as the standard Honeycomb keyboard, I do like having the numeric row visible above the rows of letters. Nuance's T9 Trace is still supported by the keyboard (Swype-like continuous text input) although I'm not personally a fan. You can disable Trace as well as revert to the stock Honeycomb keyboard if you'd like.

It would be pretty hard to beat the visuals of Infinity Blade II on the ipad2. The game looks amazing.TrackSmart - Thursday, December 1, 2011 - link
Anand,Just a heads-up, as I know you had to get this review out the door quickly: It would be really useful to put the weight of the tablet AND keyboard dock prominently on the first page (maybe in the chart?). This would make it easier to compare the total travel weight to ultraportables and netbooks.
I'm guessing that we're talking about 2.6 pounds from what I could find online. And you'd end up with some serious battery life (18 hours?) compared to even the longest running Zacate (or Atom) laptops/netbooks. If only the software and hardware capabilities were as good...

Asus looking good but tablets can't replace x86 PCs yet. I hope Asus launches a 15" Zenbook with 1080 display and maybe even a quad core Ivy bridge. I don't mind if it's thicker but I want something to compete with the rumor Macbook Air 15".HighTech4US - Thursday, December 1, 2011 - link
Will the ASUS Eee Pad Transformer Prime be retested here when ICS (Ice Cream Sandwich) is released for it?My understanding is that there are improved graphics drivers and other improvements in the OS that will improve on the results shown here.

Hi Anand,It seems that the results of the Ipad 2 and Transformer Prime are quite different in GLBenchmark 2.0.3 Egypt (tested by PCworld) vs. what you have found based on the vs. 2.1 of the same benchmark. Could you comment what may be the reason for the differences?
"The most significant result in our gaming performance tests: The Transformer Prime logged 53 frames per second, the highest frame rate we've seen on the GLBenchmark 2.0.3 Egypt test with no antialiasing. This result topped the Apple iPad 2's previous record of 46 fps, and it just crushed the Android masses we've tested, which averaged 18 fps and topped out at 34 fps (for the 7-inch Acer Iconia Tab A100)."

Also wanted to add that other sites show much longer battery life for the Transformer. I understand that the battery life depends on use but could be that your unit is a dud in not only in case of WiFi but also battery, so I wonder if you would be willing to repeat the battery test?Anand Lal Shimpi - Thursday, December 1, 2011 - link
I'm already on it :) Got a new Prime in this morning and battery life is looking much better already.Take care,
Anand

The tests in the article were done using an off-screen resolution of 1280x720. This allows all devices to be tested at the same resolution -- thus measuring the relative rendering performance of the SoC.Looking at the results on GLBenchmark's own website:
http://www.glbenchmark.com/result.jsp
Correlate to what is posted in the article.
The ones posted by users of Tegra-3 devices:
http://www.glbenchmark.com/phonedetails.jsp?benchm...
Also correlate with the results of the article. I suspect that version 2.0.3 may stress different parts of the GPU or that PC World got some pretty bad results.

Well I usually do not play games off-screen :) Anyway, I am still puzzled what is causing the huge difference between the 2.0.3 Egypt vs. 2.1 (assuming both test were done correctly).Also while comparing Ipad 2 at theoretical 720p has merits in synthetic testing in practice you can not see more than 1024 by 768 pixels on the Ipad 2.
I am also wondering if GLBenchmark better than lets say 3dMark for desktop? 3D Mark scores do not always correlate perfectly with real games experience due to optimizations for particular card and also because synthetic testing is not a perfect substitute for real games to start with. So I am not overly concerned about the scores more about what have changed between the GLBenchmark versions.
metafor - Thursday, December 1, 2011 - link
Absolutely. But unfortunately few games for mobile if any offer time-tests and there is no equivalent framerate tool like FRAPs to measure framerate in real games.So synthetic benchmarks will have to do for now.
As for 2.0.3 vs 2.1, GLBenchmark's website doesn't give all too much info except that it includes the off-screen mode as well as "high quality" versions.
But it does mention that 2.1's throughput tests -- which I don't think impact Egypt -- perform warm-up loops in order to cache a lot of its data before measuring GPU throughput.
Other than that, I'm not really sure what changed.
